Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall
and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If
moisture is present, it mu st not b e a llowed to remain between the she ets. Separat e the sheets or panels
immediately and wipe them down. Spray with a light oil or diesel fuel.
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored
in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so
that they are raised above the groun d and vegetation. Any stacking and spacing mat erials sho uld not be
corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the
bundles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of
moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing
moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they
do not fall over and cause injury.
If “white rust” or “wet storage sta in” occurs, contact the manufacturer immediate ly about ways to minimize
the adverse effect upon the galvanized coating.
